Answer:
The average speed on this trip was 46.15 mph. The correct option is A.
Step-by-step explanation:
In order to calculate the average speed, we need to apply the following formula:

We were given the distance between the two cities in miles, therefore we can directly apply it to the expression. Although the time was given in the hh:mm 12 h format and we need a diference in hours, so we will convert that as shown below:


The elapsed time of the trip is the difference between these:

We can now apply it to the formula:

The average speed on this trip was 46.15 mph. The correct option is A.
Answer:
Option 2 is correct that is
and
and 
Step-by-step explanation:
We have been given with the expression 
We will simplify the given expression by factorisation we will get
Taking x as common from first two terms in numerator and 2 from last two terms in numerator
Similarly, take x common from first two terms and 9 from last two terms in denominator we will get

After arranging the terms we will get 
Taking out the common factor which is (x-12) from numerator and denominator it will get cancelled we will get

Hence, Option 2 is correct that is
and

Answer:
x=-6, y=1
Step-by-step explanation:
Let's solve your system by substitution.
y=x+7;−2x−11=y
Step: Solve y=x+7 for y:
y=x+7
Step: Substitute x+7 for y in −2x−11=y:
−2x−11=y
−2x−11=x+7
−2x−11+−x=x+7+−x(Add -x to both sides)
−3x−11=7
−3x−11+11=7+11(Add 11 to both sides)
−3x=18
−3x/
−3
=
18/
−3 (Divide both sides by -3)
x=−6
Step: Substitute−6 for x in y=x+7:
y=x+7
y=−6+7
y=1 (Simplify both sides of the equation)
Answer:
x=−6 and y=1
